That's fascinating. Just think about printing "without" gravity. There will be no need for supports, no overhang issues, perfect bridges of any length and perfect ceilings of any size. Imagine what our prints could do if we had antigravity chambers just like we have climate control chambers. And, since deposition is a "contact" process, it should work perfectly. If it were not, then there would be plastic streams of spaghetti all over the place.

I wish I could go with them and play with it.
